With GPL, you're programming Freedom. With MIT, you're programming for free.

Context:
Permissive licenses (commonly referred to as "cuck licenses") like the MIT license allow others to modify your software and release it under an unfree license. Copyleft licenses (like the Gnu General Public License) mandate that all derivative works remain free.
Andrew Tanenbaum developed MINIX, a modular operating system kernel. Intel went ahead and used it to build Management Engine, arguably one of the most widespread and invasive pieces of malware in the world, without even as much as telling him. There's nothing Tanenbaum could do, since the MIT license allows this.
Erik Andersen is one of the developers of Busybox, a minimal implementation of that's suited for embedded systems. Many companies tried to steal his code and distribute it with their unfree products, but since it's protected under the GPL, Busybox developers were able to sue them and gain some money in the process.
Interestingly enough, Tanenbaum doesn't seem to mind what intel did. But there are some examples out there of people regretting releasing their work under a permissive license.

When I think of Copyleft licenses, I just think of it as "Use this program as you see fit, but if you share/redistribute it, you may not add any restrictions to it."
I don't understand why there are communities that hate GPL so much. It is such a powerful license that practically guarantees that the program will be free for any who wants it, it just won't allow someone to add restrictions to it.
I've heard arguments against the GPL like: "It's too restrictive!" Only if you want your program to be muddled with any kind of program that doesn't respect freedom. Saying the GPL is too restrictive to developers is like saying the 13th amendment of the US Constitution is too restrictive to slave owners.
I'm going to guess because of the tools that don't use LGPL.
Which makes them quite limiting and kind of controversial since you have to adopt their license from my understanding, even if used as a library.
I try and use LGPL on all my projects since it allows others to use the Library as a library, and anyone that wants to modify or use the source has to copy left.
